Using a Sierra-era Macbook Air to connect and view the screen of my 2019 iMac running Mojave. Screensharing works fine--for a while. Using 5G so very little lag.
What happens, without fail, is that after 2 hours I'll get bounced out of screensharing. If I go to my 2019 iMac, it will still be running--for a few minutes--but then it will freeze and the only way out is to force a shutdown using the power button. The mouse will still move the cursor but nothing will click and the screen itself is frozen.
I can replicate this every time. The other day I logged out of screensharing and went to work on the iMac and it still eventually froze up--requiring the same forced restart.
Is this just an issue of compatibility among the macOS generations? Or some Mojave bug where screensharing begins some cascade of horribles that eventually results in a hang?
